I started a new workout routine after being in a really bad funk. I've lost 65 pounds so far and I need to lose 56 more to be at my goal weight of 140. I'm combining 4 30 day challenges that focus on squats, push ups, abs, and legs. I'm also walking a ton, but I'm gaining weight?! I feel so discouraged and gross, I haven't gained weight in quite awhile. What is going on?
